1. A route search device for searching a route from a starting point to a destination, wherein the route includes a plurality of sections, the device comprising:
- a parameter calculator for calculating a parameter of each section in the route based on road information in a map data;
a driving repetition information obtaining element for obtaining driving repetition information in each section from an external server, wherein the server calculates a driving repetition of vehicles in each section based on traffic information when the server receives the traffic information from vehicles for collecting the traffic information regarding a road;
a road type determination element for determining a road type in each section;
a parameter changing element for increasing a parameter of first one of the sections when the driving repetition of the first one of the sections is smaller than a first parameter threshold, and the road type of the first one of the sections is a narrow street or an ordinary road, wherein the driving repetition of the first one of the sections is determined based on the driving repetition information; and
a route search element for searching the route to minimize a total of parameters of the sections in the route,wherein the parameter changing element maintains the parameter of first one of the sections when the road type of the first one of the sections is a highway.

8. A route search device for searching a route from a starting point to a destination, wherein the route includes a plurality of sections, the device comprising:
-
a parameter calculator for calculating a parameter of each section in the route based on road information in a map data; a driving repetition information obtaining element for obtaining driving repetition information in each section from an external server, wherein the server calculates a driving repetition of vehicles in each section based on traffic information when the server receives the traffic information from vehicles for collecting the traffic information regarding a road; a parameter changing element for increasing a parameter of first one of the sections when the driving repetition of the first one of the sections is smaller than a first parameter threshold, wherein the driving repetition of the first one of the sections is determined based on the driving repetition information; and a route search element for searching the route to minimize a total of parameters of the sections in the route, wherein, when the driving repetition of vehicles of second one of the sections is zero, the route search element set the second one of the sections not to be available to pass.
